AUTOMATIC GATE.

SPECIFICATION forming part of Letters Patent No. 288,601, dated November 13, 1883.

Application filed July 10, 1883. (No model.)

To aZZ whom it may concern Be it known that we, WILLIAM THORNTON and ALFRED FERRIS, citizens of the United States, and residents of Elkhart, in the county 5 of Elkliart and State of Indiana, have in vented certain new and useful Improvements in Automatic Gates; and we'do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, andin whichi I Figure l is a perspective view of our improved automatic gate, showing the gate closed; and Fig. 2 is a perspective view of the same in an open position.

Similar letters of reference indicate corre- 29 sponding parts in all the figures.

Our invention has relation. to automatic gates; and it consists in the improved construction and combination of parts of the same, as will be hereinafter more fully described and claimed.

In the accompanying drawings, A represents the frame of the gate, which has a suitable pauel, A, the top barof the frame of the gate having a longitudinal vertical slot,

,0 A, extending from its rear end to about the center of the said bar, for the purpose hereinafter described.

H represents the fence post, to which a latch of any suitable construction is attached,

5 the said latch serving to hold "the gate in its closed position.

B B represent two uprights or standards, between which the gate slides when opened. One ofthe said uprights is secured in the 0 ground a distance on one sideand to the rear of the other upright corresponding to the thickness of the gate, so that a line drawn between the axes of the posts will form an angle of forty-five degrees to the plane of the gate when itis entirely closed or opened. The tops of the uprights are connected by a cross-beam, B, having one of its ends extended out beyond the top of the post B. To the under side of the cross-beam B, bet-ween the two uprights, is pivoted the end of a downwardly-proj e'cting rod, 0, which passes throu gh the longitudinal slot A in the top bar of the gate, and has its lower end pivoted to the lower bar of the gate.

To the outwardly-projecting end of the beam 5 5 B is hung a pulley, D, through which the operating-rope E runs. This rope is fastened at one end to the forward part of the top bar of the gate, and has secured upon its free end a weight, F.

hen it is desired to open the gate, the latch which serves to hold the gate,in its closed position is raised or opened, when the weight F will slide the gate back, and, by reason of the pivoted rod 0 sliding in the slot 6 A, and of the peculiar arrangement of the uprights B B, the gate will be swung around at right angles to its former position, so as to leave the entire space-which it previously closed free for the passage of the vehicle, as shown in Fig. 2 of the drawings.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of our improved automatic gate will readily be under- 7 stood without requiring further explanation.

It will be seen that our improved gate is simple in construction, easy to operate, and, being devoid of all complicated mechanism, I is not liable to break or get out of order, while by constructing it to operate in the manner described the gate will be swung entirely out of the way of the passing vehicle.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States- I The combination of the gate .A, having a longitudinal vertical slot, A, extending through the rear half of its upper bar, uprights B B, one of which is placed on one side 0 and to the rear of the other, as described, cross-beam B", connecting the upper ends of the uprights B B together, rod 0, passing through the longitudinal vertical slot A, and

pivoted at one end to the center of the cross. 5
